This invention relates to baling presses, and it is an object of theinvention to provide a device of this kind which can be either manuallyoperated or power operated.

It is also an object of the invention to provide a device of this kindembodying a reciprocating plunger together with means whereby saidplunger may at will be rendered inoperative at any point of its strokeand which is particularly desirable in the event of accident.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved balingpress whereby certain important advantages are attained and the devicerendered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more full set forth. I

The novel features of my invention will hereinafter be definitelyclaimed. 7

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein i Figure 1 is a view in side elevation of a,

baling press constructed in accordance with an embodiment of myinvention;

Figure 2 is a view in top plan of the device as herein disclosed;

Figure 3 is an enlarged fragmentary view partly in section and partly inelevation illustrating in detail the mounting of one ofthe bale holdingdogs;

Figure l is a longitudinal vertical sectional view taken through thedevice as herein disclosed with certain of the parts in elevation;

Figure 5 is an enlarged fragmentary view partly in vertical section andpartly in elevation illustrating the mounting of the end lever togetherwith the parts associated therewith V Figure 6 is a fragmentary View inbottom plan of the rock arm for normally maintaining the plunger inoperative engagement with the power wheel.

As disclosed in the accompanying drawings, B denotes a baling chamberdisposed on a gradual slope from front to back to reduce friction of thebale as it passes therethrough, and the forward end portion of thechamber 13 in its top is provided with a conventional feeding opening 1.The rear or discharge end of the chamber 13 is adapted to be closed bythe swinging door D held in closed position by. a latch 3 coacting withan outstanding arm 4 carried by the door D.

The side walls 5 at the forward end of the chamber B are provided withelongated slots termediate offset part or crank 10 with which en agesa.spring pressed arm 11 whereby the dog is normally maintained projectedwithin the chamber B yet may be forced outwardly therefrom to permit therearward passage of a follower F and thehay or kindred material beingcompressed by theplunger P..

The bottom 12 of the chamber B is continued a desired distancein advanceof the open forwarder front end of the chamber and, as herein disclosed,said extended portion of the bottom 12 is supported by a sill 14. Theplunger P is of a reciprocating type and travels over and along thebottom 12 of the chamber B and is provided in its side marginal portionswith the slots 14 to permit the plunger to readily pass the portions ofthe dogs 7 projected within the chamber B upon travel of the plunger Pin either direction. To further facilitate the proper entry of theplunger P within the compression portion of the chamber B, a roller 15is rotatably supported between the side walls of the chamber B in theupper part thereof and immediately adjacent to the inner or rear marginof the opening 1.

The plunger P has extending outwardly from its side faces the trunnions16 upon which are mounted the rollers 17, said rollers working withinthe longitudinally disposed 100 .6 through which work the horizontallyother mechanism. associated therewith.

The plunger? has extending forwardly therefrom an elongated member orbeam 19, said member or beam 19 and plunger P con stituting a rigidstructure with the member or beam arranged centrally of the plunger P.The member or beam 19 has its outer portion bifurcated and at oppositesides of the kerf 20 the member or beam 19 is provided in its upper facewith the racks 21 with which engage the oppositely and laterallydirected trunnions 22 carried by a wheel 23. The trunnions 22 havemounted thereon anti-friction sleeves 24 and the wheel 23 is rotatablymounted upon a supporting shaft 25 carried by and bridging the spacebetween a pair of upstanding posts 26 anchored to the sill 14. Thetrunnions 22 are arranged in a partial circular series. and are of anumber suflicient upon a single rotation of the wheel 23 to force theplunger P inwardly of the baling chamber B and at the same timepermitting the desired return stroke of the plunger P. This returnstroke is accomplished by a retractile member-27 of requisite tensionand herein disclosed as a coil spring, having one end suitablyanchoredto the lower portion of the plunger P and its opposite endportion suitably anchored to the outer end portion of the sill 14.

It is believed to be obvious that as the plunger P is forcedinwardlythis retractile member or spring 27 is placed under tension so that asthe end trunnion 22 leaves the member or beam 19 upon its compressionstroke,

. the plunger P will immediately return to a position in advance of theopening 1. Upon continued rotation of the plunger P hay or kindredmaterial is effectively baled in a Well known manner within the chamberB.

The member or beam 19 is normally maintained in a raised or elevatedposition for properengagement of the trunnions 22 with the racks21through the instrumentality of a vertically swinging rock arm 28rotatably su'pportechas at 29, upon the sill 14. The upper or free endportion of this arm 28is continued by a cross member 30 underlying thebeam or member 19 and carrying an antifric'tion sleeve or roller 31which has direct contact with said member or beam 19 from below. Thepivoted end portion ofthe arm. 28 iscontinued by a stub shaft 32 throughwhich is fired an upstanding rock arm 33. The upper portion of this arm33 is connected by a retractile member 34, herein disclosed as a coilspring, with a lever 35. This lever 35 is normally disposed in avertical direction and has its lower end portion pivotally connected,

as at 36, with a side wall of the chamber B 37 the rock arm 33 willbecome ineffective and the member or beam 19 will drop sufficient todisengage the racks 21 from the trunnions 22. The wheel 23 works withinthe kerf 20 of the member or beam 19 and at its periphery is providedtherealong'with the teeth 38 with which is adapted to engage a gravitypawl 39 pivotally connected, as at 40, with'a hand lever 41. The handlever 41 at its lower portion is provided with the arms 42 provided attheir free, ends with the sleevesor collars 43 freely mounted upon theopposite end portions of the hubs44 of the wheel 23. As the hand lever41 is oscillated the wheel 23' will be manually driven to effect thedesired compression stroke ofthe plunger P. Retrograde movement of thewheel 23 is prevented by a holding dog 45 pivotally mounted, as at 46,

and engagii'ig by gravity the teeth 38 of the wheel Rotatably supportedby a side wall of the device adjacent the wheel 23 is a shaft 47provided with a rock arm 48 adapted, upon rotation or rocking movementof the shaft 47 in one direction, to contact from above with the memberor beam 19 so that the member or beam 19 may be thrown out of operativeengagement with the wheel 23 at any time duringthe movement of theplunger Pand which is of especial importance or advantage in case ofaccident. Theshaft 47 at its-outer portion is provided with an elongatedoperating lever 49 which may be readily grasped and manipulated by anindividual. The rock arm 48 is normally maintained in position out ofcontact with the member or beam 19 by a resilient holding arm 50extending outwardly from a side wall of the device and upon which thelever 49 rests from above. I?

In case of emergency it is only necessary that this lever 49 be presseddownwardly, the resiliency of the arm 50 readily permitting suchoperation.

The side Walls of the chamber B at their forward ends are continued bythe horizontally disposed frame members 51 which are also suitablyconnected to the upstanding posts 26. These frame members 51 areprovided with bearings 52 for the parallel shafts spaced gears 56 and57.and upon proper adeam justment of said shaft 54 the gear 56 isbrought into mesh with the peripheral teeth of the wheel 23 while thegear 57 is brought into meshwith a gear 58 carried by the shaft 53. Bythis means the plunger P may be power driven.

If preferred, the pulley may be attached directly to the shaft 54 and inwhich event the shaft 53 is unnecessary but by use of these thrown intoinoperative position when desired.

As is particularly illustrated in Figure 4 it is to be noted that thetrunnions 22 are substantially in a spiral arrangement with the high oroutermost trunnion first engaging the member or beam 19 to force theplunger P inwardly. By this particular arrangement of the trunnions 22the power imposed upon the plunger P is increased and at the times suchincrease is required.

Inwardly of the frame members 51 are the supplemental horizontallydisposed frame members 60 each being of a length, as illustrated in Fiures 1 and 2, to extend beyond the outer end of the members 51. Thesemembers 60 are arranged at opposite sides of the wheel 23 and below thehub thereof and coact with the side marginal portions 61 (Figure 5) tolimit the upward movement of the member or beam 19 of the plunger P onits back or returned stroke so that the plunger will not interfere withany of the parts of the device.

The outer or extended end portion of each of these members carries adepending latch bar 62 with which is adapted to engage an upstandingcatch 63 carried by a side face of the member or beam 19 of the plungerP as illustrated in Figure l of the drawings.

The plun er P, under power, passes into the feed chamber of the press asfar as required to compress the hay or the like to the desired density.As hereinbefore described, the plunger P is automatically released andby means of the coil spring 27 it is pulled backward. Upon its returnthe plunger P will strike the wheel 23 with sufficient force to permit arebound of the plunger P to reenter the feed chamber of the press adistance sufficient to obstruct, in a measure, the delivery of the hayor the like into the feed chamber. However, by provision of the bars 62and catches 63, upon this return of the plunger P the engagement of thecatches 63 with the bars 62 will prevent such rebound.

* As the trunnions 22 engage the racks 21, the

catches 63 will be released from the latch bars 62, thus permitting thedesired working stroke of the plunger P. 1 1

From the foregoing description it is thought to be obvious that a balingpress constructed in accordance with my invention is particularly welladapted for use by reason of the convenience and facility with which itmay be assembled and operated, and it will also be obvious that myinvention is susceptible of some change and modification withoutdeparting from the principles and spirit thereof and for this reason Ido not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice except as hereinafter claimed.
